At some point in the deep past, humans may have come frighteningly close to disappearing altogether. Here’s what we know, ...
Tens of thousands of years ago, the first wave of a worldwide tsunami now known as the “Sixth Extinction” swept across the ...
One of Earth’s earliest mass extinctions wiped out most ocean life during a sudden global ice age. From the ruins, jawed vertebrates survived, diversified, and transformed the course of evolution.
About 445 million years ago, Earth’s oceans turned into a danger zone. Glaciers spread across the supercontinent Gondwana, ...
Speciation and extinction are the twin engines that have sculpted the diversity of life on Earth. Speciation, the process by which new species arise from ancestral populations, is driven by a mixture ...
The extinction of the largest dinosaurs to walk the Earth may have played a critical role in creating an environment that helped fruits evolve, thereby indirectly shaping the evolution of our own ...
A rapid climate collapse during the Late Ordovician Mass Extinction devastated ocean life and reshuffled Earth’s ecosystems. In the aftermath, jawed vertebrates gained an unexpected edge by surviving ...
In a new study in Geology, researchers calculated how long it took for novel single-celled marine species to appear after the asteroid impact, and it’s surprisingly fast.
